Calculator

Aspect ratio calculator

Matching dimensions for any ratio, plus how much of a camera frame survives the crop.

Matching height—
Crop from a 6000×4000 (3:2) frame—
Crop from a 5184×3888 (4:3) frame—

How it works#

Height = width × (ratio height ÷ ratio width). Cropping a 3:2 photo to 4:5 keeps 83% of the pixels.
